Patented Oct. 29, 1935 ITED STAT PATENT OFFICE COMBINED WINDOW SCREENAND VENTILATOR 2 Claims.

The invention relates to a window ventilator, and has for its object toprovide a box adapted to be disposed between the lower sash and windowstool or ledge, said box being arranged to freely permit air and lightto enter the room but to exclude rain and intruders, insects, etc., andto control said air, and having adjustable extensions at the ends sothat it may have lengths equal to the widths of window sash so as to beeasily detachably fitted to any type window to prevent displacement.

Another object is to provide a guard of the character described wherebythe current of air admitted through the window will be deflectedupwardly and its quantity controlled to protect the occupants of theroom from the direct draft and outside atmospheric changes heretoforeannoying.

Another object of the invention resides in the provision of a Windowventilator which may be cheaply constructed and completely closed whendesired, which may have a removable glass member and which will haveshelf means for the lower sash to rest thereon to prevent drafts usuallypassing under the sash.

With the foregoing and other objects in View, the invention presents anew and novel construction and combination of parts described and shownin the accompanying drawing forming a material part of this disclosureand in which,

Fig. 1 is a top plan view of the device Fig. 2 is a front view thereof,

Fig. 3 illustrates, in perspective, a fragmentary portion thereof,

Fig. 4 is a sectional View through the venti1a tor taken on the line 44Fig. 1.

In the drawing the numeral I, designates the side member of a windowcasing having the inside grooves 2, in which the sash 3, slides, and thebottom ledge 4. These parts are of conventional construction.

In the form shown the ventilator I0, is box shaped and must be made ofdifferent lengths to accommodate window openings of varying widths. Myslideable end pieces II, and I2, provide reasonable amount ofadjustment, said pieces being slideable in the groove [3, formed betweenthe cover l4, and the box end flanges. Formed integrally with the coverI4, is the extending shelf 15, providing resting means for the sash 3,and arranged to prevent drafts under said sash, the back l6, of saidextending shelf aiding in this respect.

The cover I4, is provided with spaced screened openings l1, and mountedslideably on this cover,

as at 33, is the shutter l8, provided with openings I 9 adapted to bemoved into and out of registration with the openings II, by means of theknob or handle 20, carried by or formed integral with said shutter.Stops 2!, are provided limiting the movement of the shutter to fromcompletely closed to open position. The screen 22, may be formedintegral of the cover, or separately, of a foraminous material, as shownin Figure 4. When separately formed the screen 10 may be fastened to thecover by preferably pointed depressed tongues 23, formed integral withthe cover and bent around or through the screen holding it in place.

The glass 2 is from the room side, preferably removably mounted to theventilator, grooves being arranged at the ends of the ventilator as at25, and at the bottom as at 26. It is readily seen that light is notobstructed by my ventilator and that the arrangement and fastening ofthe glass prevents water, drafts etc., from entering the room.

The bottom 28, is formed so as to fit the easing to exclude water, etc.,from entering the room and its lower edge 29, is preferably turneddownwardly and adapted to fit against the other edge of the ledge 4.

The outer vertical wall 30, of the ventilator I0, is provided with oneor more apertures 3|, to act as the intake manifold and the air isdirected upwards through the adjustable and screened ports I! and I9, into the room. It will be seen that any draft of air will be deflectedupwardly into the room, this obviously being a desired feature.

In use the ventilator is located inside the window on the ledge 4, withthe flange 29, resting against the outer edge of said ledge and the endpieces II and I2, resting in the sash grooves 2. 4 The lower sash isthen pulled down to rest on the shelf i5, and on said end pieces, thusmore firmly holding the ventilator in place. The shutter I8, is adjustedas required. The ventilator may be fastened to the sill with suitablefastening means at the bottom and may also look itself to the sash bymeans of a locking means such as at 32.

As many apparently widely different embodiments of the invention couldbe devised without departing from the scope thereof it is intended thatall matter contained in the above description or shown in theaccompanying drawing shall be interpreted as illustrative and not in alimiting sense.

I claim,

1. In a ventilator rectangular in cross sectional contour having anaperture in the outer side and screened apertures in the cover; ashutter, having openings therein, horizontally slidably mounted intracks formed integral with the cover and adapted to be moved into andout of registration with said screened cover apertures; a sashsupporting shelf member integral with the cover set below the top of theventilator; a deflector member on the inner side upwardly andunobstructively removable from its position in the ventilator permittinglateral entry into the interior of the ventilator when so removed,lendposts, slideable with respect to said ventilator, in a groove formedbetween the ventilator outer frame side and the vertical flange part ofsaid sash supporting shelf to increase the eifective length of theventilator, a base member having a flange for engagement with the windowsill, and means for locking said sash and window to said ventilator.

2. In a building window ventilator rectangular and unobstructivelyremovable from its position 10 between the back flange of the cover andsaid ventilator inner frame side permitting lateral entry into theinterior of the ventilator when the deflector is removed; end posts,slideable in 15 a groove, inherently formed by the ventilator outerframe side and the vertical flange part of said sash supporting shelf,to increase the effective length of the ventilator; a base member havinga flange for engagement with the window 20 sill; and means for lockingsaid sash and window to said ventilator.
